here is a theory/scenario: ( will not call it an example, until I dig thru my films, if people wan tot see this)
recently Fork had friendly collisions turned on in the " old CT Arena".....
you and your wingy went to take off same time, you having faster connect loaded was on runway and all of a sudden get a so and so has collided with you, both your FE and the server sees this, but the wingys FE never saw you there when he took off, you was no where to be found, and when the 1st guy loaded to take off he never saw the other guy, because wingy's (2nd pilot's) FE was slower loading so you both on each FE never saw the other, yet the server and the faster guy recognized the 2 being in same spot at same time...........well wingy#1 is now back in the tower, and wingy#2 is taking off wondering where the heck wingy #1 went, ROFL
best I can do describing it, am out the door for a short work day....
